Natasha Charova, the girlfriend of accused Brooklyn serial killer Salvatore Perrone, is known for dressing up with a friend in wild outfits to go dancing, a neighbor said.

“These two women would go dancing every Friday night. You should see the way they dressed,” said the neighbor, who spoke on the condition of anonymity. “[Charova] would wear different wigs, and you should see the net stockings her friend had. They liked to go the clubs.”

A friend said Perrone, 64, of Staten Island, who allegedly carried a duffel bag to the slayings, went to a club just hours after allegedly killing 78-year-old Flatbush store owner Rahmatollah Vahidipour on Nov. 16.

Sources have said that the two had a rocky relationship, and a roommate said that he once flashed a knife.

“They slept in different beds,” the neighbor said. “She sleeps in the bedroom and he sleeps on the sofa — that’s what the roommate told me.”

Charova did not respond to calls for comment, and has not been seen at her East 14th Street apartment, where cops have been posted since her paramour was busted in the gruesome serial killings.

Perrone, who was fingered by cops after surveillance footage caught him near the scene of the third slaying, copped to the killing spree after thinking he was chatting with federal agents, sources said.

And he was chatty with investigators during a marathon interrogation session — until he spoke with his daughter, a law-enforcement source said.

“When they were originally interrogating him, he was talking, and he implicated himself in the three murders,” the source said.

The alleged killer then took a nap.

“When he woke up, he spoke to his daughter on the phone and after that is when he stopped talking,” the source said.

“After he spoke to his daughter, he refused to make a written or video statement.”

Perrone was charged in the slayings of Mohamed Gebeli, 65, a Bay Ridge clothing-store owner; Isaac Kadare, 59, who owned a 99 cent store; and Vahidipour.

The three were found dead in their stores and killed with the same weapon, cops said.

The murder weapon was found in Charova’s house, cops said.

Charova is not expected to be charged, and cops say she didn’t seem to have any idea that her boyfriend was an alleged murderer, law-enforcement sources said.

Perrone had done business with the first victim, and cops believe he knew all three, sources said.

Cops are interviewing Perrone’s Staten Island neighbors to try to dig up everything they can, a police source said.

The terrified ex-wife of the alleged killer refused to talk to a reporter outside her Staten Island home.
